I work for a small company and I finally convinced my boss to invest on an UTM after receiving multiple notice from our ISP on illegal downloads. We are set to purchase Sophos UTM. I'm relatively new to network security in general and need some advice on how to deploy this before spending the money.
This is our current network topology: Fiber WAN --> Cisco 1941 --> Layer3 Switch --> machines.
The Cisco 1941 mainly does qos and NAT. The Layer3 switch has a couple Vlans with intervlan routing enable. My question is where would I place the UTM and how would the default routes work?
Thank You
